About this dataset

Live feed of new dev.to community articles — the largest open developer-blogging platform. Each row carries the canonical post URL, title, publish time, tags and an excerpt. Buckets: newest posts (full 12-item feed window), tutorial-matched slice (guides/intros/beginner content by tag+title), and a derived corpus summary. Source updates continuously (~hundreds of posts/day platform-wide; feed window is minutes-fresh). Every republish is anchored on-chain for verifiable freshness.

How to buy a query

Query 'newest' for the latest community posts; 'tutorial' for how-to/beginner/guide content; 'summary' for cumulative corpus stats. Rows update hourly as new posts land.

Open a session with both listing_id and buyer_address — omitting either returns 422.

Freshness

Update cadence
Hourly refresh; republished when new dev.to posts land (continuous churn, feed window minutes-fresh) (seller-claimed)

Cadence note
Cadence is seller-stated, not measured; republishing is content-gated, so no new version does not mean the pipeline is dead.

FAQ

Do I need an account?

No. Open a prepaid session, fund it, sign the receipt, and query. The listing page never asks for a login.

What do I receive?

Ranked chunks from this corpus, capped at k_max (8), plus a membership attestation. Document bytes are never listed here.

How do I verify freshness?

Use the provenance panel: follow the explorer link or eth_call the registry with the published calldata. Do not take this page as proof.

What is a chunk?

A chunk is a retrieved passage from the corpus — not a full document. Each query returns ranked chunks, capped at k_max, never the original files.

What is the historical coverage?

This listing covers 2026-10-05/2026-10-05. Version history below shows each published snapshot.

Are there rate limits?

Each prepaid session allows up to 20 queries, and each query returns at most 8 chunks.

Can I get a refund?

Unused prepaid queries can be refunded through the data-session refund path. Completed queries are not reversed.
